PROGRAMMING AN EMBEDDED SYSTEM IN A VEHICLE USING DYNAMIC PROVISIONING OF PROGRAM CONTROL OPERATIONS

摘要

A system for programming an embedded system disposed in a vehicle comprises an external programmer and a principal control unit disposed in the vehicle. The principal control unit is coupled for communicating with the embedded system and the external programmer. The external programmer dynamically provisions the principal control unit with program control operations that are executed by the principal control unit to program the embedded system. In one embodiment, the principal control unit is dynamically provisioned with software code from the external programmer, where the software code is executable by the principal control unit. In another embodiment, the principal control unit is dynamically provisioned with executable commands provided by the external programmer. In one example, programming is described in the context of a telematics system in which the principal control unit is a telematics control unit that oversees the operation of a plurality of embedded systems within the telematics system.
